Subcellular location [CC]Secreted. Secreted, extracellular space. Cytoplasmic vesicle, secretory vesicle. Note=Secreted via the classical ER/Golgi-dependent pathway into the extracellular medium largely as a full-length protein without the signal peptide, and not as a hydrolyzed and amidated peptide (PubMed:19193193 and PubMed:17284679). Localized extracellularly surrounding the villous trophoblastic cells. Detected in the serum.
